Surface morphology induced electrical conductivity and specific surface area of a material play a significant role to facilitate electrochemical behavior for supercapacitor application. Therefore, the synthesis step for controlling such parameters becomes very imperative and challenging. Herein, a ZnS nanoweb is deposited directly onto Ni foam with a pre‐deposited thin layer of hydrothermally prepared graphene oxide. The structure and surface morphology of the deposited ZnS is observed using XRD and SEM, respectively. The electrical conductivity of the graphene oxide supported ZnS nanoweb, determined using the four probes method, is 100.15 S cm−1. The specific surface area is 104.42 m2 g−1 as determined by BET measurements. Pseudocapacitive behavior is monitored by cyclic voltammetry, and the excellent specific capacity of 3052 Fg−1 has been found at a scan rate of 2 mV s−1, while it is 2400.30 Fg−1 according the galvanostatic charge‐discharge profile at a current density of 3 mA cm−2. Both values are significantly higher than those measured for bare GO or ZnS layers. The energy and power densities of GO supported ZnS nanoweb are determined in a three electrode setup, are 120 Wh Kg−1 at 3 mA cm−2 and 4407.73 Wkg−1, respectively. In a symmetric two electrode setup, an energy density of 20.29 Wh Kg−1 at 2 mA cm−2 is observed. Hence, both symmetric and asymmetric measurements suggest that GO supported ZnS nanoweb can be applied as a suitable electrode for supercapacitors.

Flexible, lightweight, and environment friendly energy storage devices are in high demand of modern disposable technology. This study presents the coating of directly collected lignocelluloses fibers from self‐growing plant, Monochoria vaginalis with conducting layers of polypyrrole and polyaniline. Fabricated paper electrodes were conductive, electroactive, all‐organic constituents, flexible, and can be cut with help of scissor in any shape. Paper electrodes were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis for morphology, structural, and thermal characteristics, respectively. Furthermore, fabricated paper electrodes were characterized by cyclic voltammetry to confirm the electroactive behavior and showed excellent electrochemical performance. Paper sheets comprising lignocelluloses fibers and polypyrrole coating (LC/PPy) were employed as electrodes of symmetric cell and showed specific capacitance of 230.35 Fg−1 at current density 0.25 mA g−1 for LC/PANI, while LC/PPy showed 9.042 W h kg−1 and 91.33 W kg−1 energy density and power density, respectively. This paper electrodes are highly feasible for environmentally safe and flexible energy storage applications, particularly in era of modern disposable technology. © 2018 Wiley Periodicals, Inc. J.

Supercapacitors are very exclusive among energy‐storage devices for the wearable and portable industry. Due to simplicity, abundance occurrence, good electrical conductivity, and rich redox states, metal sulfides have a significant impact in supercapacitor applications in the present decade. Sulfur is the anion, associated with metal cations, and provides substantial tunable electrochemical, electrical, physical, and chemical properties in metal sulfides. In addition, carbonaceous materials enhance the electrochemical characteristics of metal sulfides synergistically for supercapacitors. Fast and scalable synthesis and fabrication of the supercapacitor cell with low‐cost metal sulfides and heterostructures should be developed to achieve the potential applications of these hybrid glorious materials. Herein, the significant and critical discussion of metal sulfides synthesis and their hybrid with carbon electrode structures for supercapacitor applications is disclosed. The realistic synthesis of metal sulfides, basic charge storage phenomena to elaborate the electrode nature, electrochemical properties including a single electrode, and asymmetric and symmetric cells are demonstrated for comparative purposes. The market values and application of supercapacitors are also elaborated. Herein, a better understanding to fresh readers about metal sulfide hybrid electrode structures for supercapacitors is provided.
